Why Clean Rooms Are Required For Data Recovery

Different users have different views about what the Clean Rooms are and why they actually are important for data recovery. Fundamentally the Clean Rooms are safe and controlled laboratory environments, which are designed to avoid minute airborne contaminants that could be dust or even pollen.

For data recovery firms, the Clean Room is a necessary asset as hard disk repair needs exceptionally clean and secure working conditions. The airflow in Clean Room is completely clear. The Clean Rooms are also free from other harmful environmental factors as humidity, ESD (ElectroStatic Discharge), smoke, high temperature (viz. due to direct sunlight) or pressure.

The Clean Rooms are divided into different classes. With every class limiting permitted different number of dust particles per cubic meter and the maximum size of dust particles. Thus the Class 1 Clean Rooms allow maximum 1000 particles for each cubic meter.

The Clean Rooms are mainly used in semiconductor manufacturing, pharmaceuticals, hard drive recovery companies and biotech industries. The data recovery firms use Clean Rooms to ensure protected environments for storage media internals as hard drives and SSDs (Solid State Drives) in order to avoid further damage to disk internals that actually store the data viz. hard drive platters.

Why are the Clean Rooms necessary for physical Data Recovery?

The hard drive internals specifically hard disk platters, are extensively susceptible to damage from dust particles once opened. Even a microscopic dust particle could damage the sensitive platters and may separate the stored data for life. To avoid these situations, Hard Drive Recovery companies use Clean Rooms.

Hard drive technique continues apace with the drive being able to store a large amount of data but it becomes more compactly packed on disk platters and the possibilities of further damage are high. So, it would be better to find out a trusted and experienced Hard Drive Recovery company with high standard Clean Rooms and send your hard drive to it.

Along with a certified Clean Room, absolute and timely hard drive recovery also needs expertise of skillful and experienced data recovery professionals. Thus, you should send your hard drive to a data recovery company that has a team of trained and qualified recovery specialists.

Data loss due to problem in Security System

Published by admin under Data Recovery


STOP error messages in Windows NT based operating system (Vista, 2003, XP and 2000) primarily occur due to software or hardware corruption. Some software issues that might result in STOP error message are installation of a corrupted device driver, internal security issues, file system corruption and software bugs. After a STOP error message appears, the system becomes unbootable making all the data saved in the hard drive inaccessible. In such situations, a perfect solution is to restore the data from an up-to-date backup. However, in case of no backup availability or backup falling short of restoring the required data, an advanced data recovery application comes to rescue.

 

As a practical case, you encounter the below error message when you attempt to start your Windows based system:

 

“STOP: 0×00000029 (parameter 1, parameter 2, parameter 3, parameter 4)

SECURITY_SYSTEM”

The four parameters in the above error message differ due to system’s configuration.

 

Once the above error message appears, the data saved in the hard drive becomes inaccessible. Furthermore, you encounter the same STOP error message each time you attempt to boot your system.

 

Cause:

 

The above error message primarily occurs under any of the below two situations:

 

1      Some problem in internal security system of your computer

2      Device driver is corrupted

 

To avoid the occurrence of the above error message, you should always install the latest hardware drivers in your system.

 

Resolution:

 

To resolve the above STOP error message and access the data, you will need to take these actions:

 

1    Remove the new hardware (especially the chipset and video drivers) and reboot your system

2      Increase the RAM (Random Access Memory) and disk space of your system

3      Confirm the compatibility of the hardware and drivers by using Microsoft Hardware Compatibility List (HCL)

4      Select Last Known Good Configuration option while rebooting your system

 

However, if all the above measures fail to resolve the issue and the data still remains inaccessible, then you need to use advanced data recovery software. These data recovery applications employ advanced scanning methods to recover lost data from a formatted hard drive. Built with intuitive user-interface, automated recovery procedure and powerful features, these applications are as easy-to-understand and implement.
